Cool. Could you paste an example? I looked around a bit but didn’t find anything.

This is incredibly common if you’re writing Shell Script code.
Just not the same “||” notation to the operand but the very same idea.

Lua has something just like this too:

function printIt(x)
  print(x and "TRUE!" or "FALSE!")
end
print("valid") -- TRUE!
print(false) -- FALSE!
print({first="John",last="Smith"}) -- TRUE!
print(nil) -- FALSE

It just looks nicer and less weirdly-ternary in AS3. Definitely one of my favorite AS3 features now. :)

Hot dog, short circuit to the rescue! So, I guess if the first operand evaluates to anything “true” the second operand is never evaluated. Most excellent. I was always jealous that the Ruby guys have a similar shortcut for that ternary case.
